TECHNICAL FIELD

The present invention relates to sorting technology, and specifically to a parcel and article sorting system and method.

BACKGROUND ART

Parcel sorting includes dispensing packages going to different destinations to different exits through a delivery device, so as to realize unified transport of packages going to the same destination. This is especially advantageous in a order fulfillment center or shipping facility. Generally, a parcel containing articles for shipment will have a UPC, barcode, SKU, or similar that allows for identification of the parcel identity and destination.

Article sorting includes dispensing articles that come from a plurality of warehouse locations to different exits through a delivery device, so as to realize unified consolidation at a single exit or destination point of all articles in a single order going to a destination in a single package or parcel. This is especially advantageous in any type of parcel fulfillment center.

The process is very labor intensive, which increases cost, errors in processing, and increases the time for packages to arrive, all lessening the end customer experience. Additionally, packages may be damaged, mispackaged, and the like, reducing efficiency for all involved parties.

Automated sorting equipment may be useful for addressing these issues, however, sorting equipment is expensive, requires significant capital investment, takes up large portions of warehouse space, is limited in the volume of packages that can be sorted, is significantly underutilized at less than peak periods, and has a long payback in most cases due to the above factors.

Accordingly, a need exists for a solution to these problems.

The parcel sorting device 100 and the parcel collecting device 101 are embodied in many structures, e.g. quadrangle, circle, polygon and so on, and the parcel collecting device 101 and the parcel sorting device 100 preferably have substantially the same area.

In order to improve the parcel sorting efficiency, preferably, each of the parcel checking inlets 104 is provided with one parcel information acquisition device 200. The parcel checking inlets 104 are in one-to-one correspondence with the parcel information acquisition devices 200, the parcel information acquisition devices 200 are configured to acquire parcel information of the parcels to be sorted that enter the parcel checking inlets 104 corresponding to the parcel information acquisition devices 200, and the parcel information contains destinations of the parcels to be sorted.

A plurality of parcel checking inlets 104 are provided, with each parcel checking inlet 104 being provided with a parcel information acquisition device 200, such that the information acquisition and sorting of the plurality of parcels to be sorted may be performed simultaneously at the plurality of parcel checking inlets 104, so as to significantly increase the parcel information acquisition efficiency, thereby improving the parcel sorting efficiency.

In the above, there are many manners for the parcel information acquisition devices 200 to acquire the parcel information of the parcels to be sorted. Preferably, the destination information is carried in a destination address information code, the destination address information code is provided on the parcel to be sorted, each of the parcel information acquisition devices 200 includes a scanner, and the scanner is configured to scan the information code for obtaining the destination of the parcel to be sorted. For example, the parcels to be sorted are provided thereon with information codes containing destination information of the parcels to be sorted, and the parcel information acquisition devices 200 obtain the destinations of the parcels to be sorted by scanning the information codes on the parcels to be sorted, wherein the information code may be a bar code, a two-dimensional code, a radio frequency tag etc., and correspondingly, the parcel information acquisition device 200 may be a bar code scanner, a two-dimensional code scanner, a radio frequency identifier, etc., and the mobile transport device 202 may be an auto-navigating small vehicle.

According to actual demands, in addition to the destination, the parcel information may further contain information about the parcel volume, weight etc., and correspondingly, the parcel information acquisition device 200 may further include a weighing device, a volume scanner, etc.

While the parcel information is highly-efficiently obtained, in order to improve the efficiency of subsequent sorting, preferably, after the plurality of parcel information acquisition devices 200 simultaneously acquire the parcel information of the respective parcels to be sorted, the control device 201 is used to complete the analytical processing of the obtained parcel information of all the parcels to be sorted, thereby obtaining the destination information of the respective parcels to be sorted. For example, the system further includes a control device 201, the control device 201 is in connection with all the parcel information acquisition devices 200 so as to obtain the parcel information acquired by all the parcel information acquisition devices 200, to obtain the destinations of the respective parcels to be sorted.

After obtaining the parcel information, in order to improve the efficiency of the subsequent sorting processes, the system preferably further includes a plurality of mobile transport devices 202, wherein the plurality of mobile transport devices 202 are in connection with the control device 201, the control device 201 is pre-provided with parcel outlets 102 respectively corresponding to different destinations, the control device 201 is further configured to control, according to the obtained destinations of the parcels to be sorted, at least one of the mobile transport devices 202 to transport the parcels to be sorted to the parcel outlets 102 corresponding to the destinations of the parcels to be sorted, as shown in FIG. 2.

In the above, the control device 201 has already obtained the destinations of the respective parcels to be sorted at the respective parcel checking inlets 104, and the parcel sorting can be completed just by obtaining the transport paths of the respective parcels to be sorted through analysis according to the positions of the parcel outlets 102 corresponding to the destinations of the respective parcels to be sorted, and then controlling at least one of the mobile transport devices 202 to transport, according to the transport paths, each of the parcels to be sorted to the parcel outlets 102 corresponding to the destinations of the parcels to be sorted.

The analysis by the control device 201 on the transport paths of the respective parcels to be sorted is performed simultaneously. After the path analysis is completed, the plurality of mobile transport devices 202 may be simultaneously controlled, to simultaneously complete transporting of the individual parcels to be sorted, thereby significantly improving the parcel sorting efficiency.

Each of the mobile transport devices 202 is configured to load one parcel to be sorted or a plurality of parcels to be sorted that go to the same destination. Preferably, the mobile transport device 202 is configured to transport one parcel to be sorted one time, and the control device 201 sends a control instruction to the mobile transport device 202 after obtaining the destination of the parcel to be sorted that is going to be transported by the mobile transport device 202, such that the mobile transport device 202 travels to the position of the parcel outlet 102 corresponding to the destination of the parcel to be sorted.

In the above, the parcels to be sorted may be manually loaded onto the mobile transport devices 202, and the parcels to be sorted may also be automatically loaded onto the mobile transport devices 202 by intelligently controlling parcel gripping devices or the like through the control device 201. Similarly, the transport of the parcels to be sorted from the parcel outlets 102 to the parcel collecting device 101 can be performed manually, and may also be completed by intelligently controlling parcel gripping devices or the like through the control device 201.

In order to assure that the respective parcels to be sorted that are transported into the parcel collecting device 101 can be delivered in time, the system preferably further includes a detection device 204 and a transfer device 203, wherein the detection device 204 is configured to detect whether a storage device 103 is full or not and to transmit to the control device 201 the obtained information regarding whether the storage device 103 is full or not, and the transfer device 203 is configured to transfer the storage device 103 which is full according to an instruction from the control device 201. There are many options for the transfer device 203, e.g. an intelligent robot; and for another example, the storage device 103 is mounted on the transfer device 203, and the transfer device 203 is a large-scale auto-navigating vehicle and may move to a position and load and unload the parcels according to the control instruction of the control device 201, as shown in FIGS. 3 and 4.

Based on the above-mentioned system architecture, the examples of the present invention are implemented as follows:

the respective mobile transport devices, such as a forklift, transport the parcels to be sorted to the respective parcel checking inlets 104, and the parcel information acquisition devices 200 at the respective parcel checking inlets 104 acquire the parcel information of the respective parcels and transmit the acquired parcel information to the control device 201. The control device 201 performs simultaneous analysis on the parcel information of the plurality of parcels to be sorted to obtain the destinations of the respective parcels to be sorted and the parcel outlets 102 corresponding to the respective destinations, and controls the plurality of mobile transport devices 202 to simultaneously transport the respective parcels to be sorted to the corresponding parcel outlets 102. The parcels to be sorted are delivered from the parcel outlets 102 into the storage devices 103 on the parcel collecting device 101 located below, and then they are moved away from the parcel outlets 102 according to a control instruction of the control device 201 and wait for further instructions. The processes above are repeated till all the parcels to be sorted are delivered into the storage devices 103. In the meantime, the detection device 204 constantly detects whether there is a storage device 203 which is full of parcels, and when there is a storage device 103 full of parcels, the control device 201 controls the transfer device 203 to transfer the storage device 103 and placing an empty storage device 103 at the position where the transferred storage device 103 was, till sorting of all the parcels to be sorted is completed. This could also be performed by a person.

The system provides an improvement for sorting orders and packaging the same for fulfillment. The system includes a platform that is elevated proximal to a lower level, which in some embodiments may be a second platform. The platform provides a surface for transport vehicles 202 to traverse to deposit an article to a destination container 208. In operation, a device or conveyor delivers a container of articles proximal a chute 214 or other material handling system. The material handling system delivers the container of articles to an article supply location. The container may contain product that is identical or may be disparate product.

An operator may select an article from the container and image an identifier 216 positioned on the article via the acquisition device 200. Optionally, the acquisition device 200 may automatically interact with identifier 216 for article recognition. The operator may place the article on the vehicle 202, or the system and process may be set up so that such deposition of article onto vehicle 202 is automated. The acquisition device 200 may then communicate the article identifier information to the control device 201.

The article supply, namely the articles shown in the containers, may be a supply of articles that has identifier 216 on each article. The information acquisition devices 200 obtain the information contained in the identifier 216 of the articles to be sorted by identifying the information codes on the articles to be sorted, wherein the information code may be a bar code, a two-dimensional code, a radio frequency tag etc., and correspondingly, the parcel information acquisition device 200 may be a bar code scanner, a two-dimensional code scanner, a radio frequency identifier, etc.
